JEROME B. FELLOWS, OF CONWAY, NEYV HAMPSHIRE, ASSIGNOR TO THE PORTLANDLAWN SPRINKLER COMPANY, OF PORTLAND, MAINE.

TRAVELING LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 548,3 58, dated October22, 18235.

Application filed March 13, 1893.

To all whom it may concern:

Be it known that I, JEROME B. FELLOWS, a citizen of the United States,residing at Conway, in the county of Carroll and State of New Hampshire,have invented certain new and useful Improvements in Traveling Lawn-Sprinklers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in traveling lawn-sprinklers, andparticularly in lawn-sprinklers adapted to receive a forward motionimparted by water escaping from rotary sprinkler-arms.

It consists in combining therewith mechanism for automatically stoppingthe onward motion of the sprinkler, after it has traveled a specifieddistance, without stopping the flow of water out of the sprinkler-arms.

It further consists in mechanism for readily setting said stoppingmechanism, so that the machine will stop at any desired distance fromthe starting-point, and in other details of construction which will behereinafter described.

In the drawings herewith accompanying and making a part of thisapplication, Figure 1 is a bottom plan of my improved sprinkler, thesteering-wheel being removed. Fig. 2 is a front elevation of the same,and Fig. 3 is a detail in section of the automatic lever-operatingmechanism.

Same letters refer to like parts.

In said drawings, a represents the forward supporting-wheels, b theforward axle, and c the platform, upon which a stand-pipe is mounted. Onthe said platform is a standpipe (6, having a nipple e, to which theWatersupply hose may be attached. Set in said stand-pipe and adapted torotate therein is a pipef, carrying sprinkler-arms g and having openingsit inside of said stand-pipe. Rigidly attached to the bottom of saidrotary pipe is a vertical shaft '5, extending down through the bottom ofsaid stand-pipe and below the platform. The bottom of said verticalshaft is stepped in a hanger 7' and below the platform carries a worm7c. Mounted on a suitable shaft is a gear-wheel Z, adapted to mesh withSerial Ho. 465,807. (No model.)

said worm, and on the same shaft is a pinion m. Loosely set on axle hare a gear 72, meshing with said pinion m, and a sliding clutch 0,adapted to engage with the gear n, and when thus engaged to prevent saidgear from turning on said axle. It will be evident that when said clutchengages said gear the rotation of the sprinkler-arms will impart to themachine a forward motion upon the ground and that this forward motionwill continue so long as the sprinkler-arms continue to revolve.Sometimes it isiinportant that the sprinkler should travel a certaindistance and then stop. To adapt the machine to this purpose, 1 place onthe axle c a worm p and on the shaft (1 a cog-gear 7, adapted to meshwith said worm. On the side of said gear are a graduated scale and a lugs. Said gear projects up through a slot in the platform. Pivotally setin hangers u is a lever 71, adapted to engage and operate the slidingclutch 0, said lever extending up through a slot 10 in the platform andhaving pivotally attached thereto a link or, adapted to engage atcertain times with the lug s on the gear 4'. A spring y constantly tendsto force said clutch to engage with the gear at. The gear is adapted tomesh with a worm p on the axle, and a spring a constantly tends to forceit forward and hold it in engagement with the worm 19, said gear beingadapted to slide on its hearing.

The operation of my improved lawn-sprinkler is as follows: The waterescaping from the sprinkler-arms causes the pipe to rotate inside thestand-pipe. Said worm, in connection with the gears before described,causes the machine to move over the ground when the sliding clutch is inengagement with the cog-wheel on the axle, but does not cause it to movewhen said clutch is disengaged. To set the automatic stopping mechanism,force the cog-wheel 0' forward until its teeth are released from theworm on the axle, as shown in Fig. 3 in dotted lines, and then turn saidcog-wheel until the figures denoting the number of feet the machine isto travel before stopping comes uppermost, and allow the cog to returninto mesh with said worm. The cogwheel 1' is timed with respect to theworm on the axle of the supporting-wheels, so that each revolution ofthe supporting-wheels turns the ICO cog-Wheel one cog space. Thus if thesprinkler is to travel a space equnl to sixty circumferences of thesupporting-wheele turn the cog-wheel until No. (it) is outop,n11 ltl1euwhen the co; is turuetl sixty cog spaces the lever will disengage theclutch and the machine will stop; but the rotary arms do not.

My improved automatic stopping mechanlSIll is adapted to an travelinglawn-sprinkler which is operated by Writer escaping from rotarysprinkler-arms, and I do not wish to limit myself to the pnrtieulnr formof traveling iawn-sprinller herein described, nor ilol wish to conlineniisclt' to the particular nrrnngeiueut of the mopping niechnuism hereindescribed.

The advantages of in -7 improved lawnsprinltlcr over those new in useare that the sprinkler may be nnule to sin :intoinnticn ly at any le irel point. Without at the Sil-lllQ time shutting off the .1: er null thatit can be readily and quicliiy to stop at any tles'rcil point.

Having; thus described my invention and its use,1 claim- The combinationwith a traveling lawn sprinkler having rotary sprinkler arms, a ro tnryvertical shaft adapted to be rotated by snitl arms and hnving a- Worm onits lower extremity meshing with gear for propellii the machine upon theground, of a norm on the axle, gear mounted in asuitable frame, meshingwith said Worm and having a, grznlir nteil scale and n lug on the sidethereof, a lever pivoted in the machine frame, a clutch on the axleadapted to engage the gear on snitl axle null a link connecting snitllever 21ml said lug, substantially as and for the purposes set forth.
